Trying to build PHP 7.3.0alpha1 on macOS 10.13 with the ldap extension results in failure during linking. The macOS library for ldap (/usr/lib/libldap.dylib) does not contain some of the new symbols used in the 7.3 ldap changes.

Test script:
Output from configure script run is available at

Output from the make process is available at

Expected result:
Build success or configure failure

Actual result:
Configure success, build failure at link.

make: *** [sapi/cli/php] Error 1

Côme, could you please have a look at this issue?

First, the documentation says OpenLDAP 2.4 or newer is needed:

There was a discussion and a patch to make it build with solaris LDAP but it was for PHP 5.6 IIRC, not sure it’s still building:

Which changes would be needed to make it build with libldap.dylib?

libldap on macOS is a fork of OpenLDAP, claiming to be 2.4.28, although there are clearly some pieces of the API that have been taken out or disabled. I added a patch to the bug that just adds some configure checks to these functions and add guards around them in the source. It may not be the best solution, but I was at least able to fully compile with it.
